Water Filter Cartridges, Replacement Filters
Water Filter Replacement Cartridges for home, whole house, commercial and industrial applications. We carry a number of "filter inserts" that are known in the industry as "cartridges". Filter Cartridges below are separated by size and application. Products are listed in the following order: 10"x2.5" filters, shower replacement cartridges, 20"x2.5" filters, 10"x5" (10x4.5) filters, 20"x5" (20x4.5) filters, inline and other sizes. Please browse our catalog or use Search function if you know model number.
How to identify which replacement cartridge you need?
Look for Brand and Model number written on your system. Also, look for any filter models that can be written on each individual housing for systems that use more than one filter. You may be able to identify cartridges by system model. If you are unable to get any product numbers, remove each cartridge (or at least one) from its housing. For round cylinder filters, measure width and diameter, it should give an indication whether your filter is of standard size. For instance, a 10"x2.5" standard filter may measure 9 7/8" x 2 1/4" (and up to 3" in diameter). Standard sizes are 10x2.5, 20x2.5, 10x5 (10x4.5) and 20x5 (20x4.5) inches (first number is length, second diameter).
